Oil Cooler - Engine & Oil Transmission Cooler
These oil coolers are equally suitable for cooing torque converter, automatic transmission and engine oils. Being water cooled they have the advantage of freedom from accidental damage and also encourage quicker warming up of the oil, a feature which is particularly valuable in cold climates. The tube stack is fully floating so that thermal stresses are minimized and it can easily be removed should cleaning be necessary.
The cooler should be fitted into the engine water circuit between the bottom tank of the radiator and the water inlet conneciton on the engine as illustrated on page 3, the radii of the water pipe bends should be as large as possible to reduce the pressure drop. Also indicated on page 3 are the approximate capabilities of the various coolers for torque converter applications. This information is only intended as a general guide as the factors affecting the choice of oil cooler are complex. In the case of engine oil applications we are not able to give any general recommendations, but proposals can be submitted on receipt of details of the particular engine.
Typical examples of oil coolers fitted to torque converter transmissions with an oil inlet temperature of 110ºC and a water inlet temperature of 80ºC.

Removal of the screws around the periphery each end will allow the end covers and teh seals to be removed. Following this operation the tube stack can be withdrawn from either end of the body. When assembling the oil cooler, new “O” seals should be fitted and the end screws must be tightened to torque settings given on the drawings.
